Upgrading From Server 2003

[ncitom]

I'm trying to clone a working Server 2003 with new hardware and upgrading to Server 2008 64bit.

The existing server is a single Primary Domain Controller with two NIC cards -- one connected to the internet and the other connected to a small internal network. It uses RRAS to allow VPN access to the internal network, and provide an internet proxy for any machines on the internal network.


I've installed Server 2008 standard with all latest service packs on the new machine and it basically runs.
It has DNS ,DHCP and RRAS running. As a VPN server, it allows connection to file shares and the internal network. If I run from the attached keyboard, I can get access to both the internet and intra-net fine. So far, so good.

The one issue I can't seem to figure out is how to allow the clients on the internal network get access to the internet. Clients can connect to the server and access to the internal network is OK. For example I can ping something on the internal network, but if I try to ping something like hp.com, it doesn't even resolve the address.

The old server is running ISA, but I understand that is not compatible with Server 2008. So the basic question is 'Do I have a configuration problem or do I need to install something else'?

It sounds like a configuration problem, probably in RRAS. Did you enable NAT in RRAS? If you were using ISA as a proxy on 2003, you may not have set up NAT separately.

Yes NAT is configured in RRAS (It was in the old Server too). Both controllers and the internal interface are defined. I've attached a screen shot showing some of the settings which I believe are correct.

I've done some reading and Microsoft is now pushing something called Forefront TMG to do the ISA function. I tried to download it and install, but unfortunately it cannot be installed on a DC. Since I only want one server when complete, that product is useless to me.

Never-the-less, it seems that I shouldn't need anything exotic to simply pass through internet requests and replies.

Is anyone doing a single server 2008 with the server doing the proxy function?

Success!

I upgraded to R2 and still had the same problem, but it gave me a few events that I hadn't seen before.
It turns out I had two different problems:

1. NAT was nearly right, but I mistakenly added an incorrect entry for address pool. The correct setting was to have none.
2. DHCP had an authentication error and was pointing to the wrong DNS server address.

Anyway it works fine now. Thanks for all inputs.

I have a server running 2003 and I want to set up the service so that the server downloads the updates and pushes them out so that it won't use all my bandwidth since i only have t1 line. so please help!

Briganca, it sounds like you want to install Windows Software Update Services (WSUS). That link is for a word document with step by step instructions.
